      <h2 id="getting-started">Getting Started</h2>

      <p>ngx-bootstrap contains all core (and not only) Bootstrap components powered by Angular. So you don't need to include original JS components, but we are using markup and css provided by Bootstrap.</p>

      <h2 id="installation-instructions">Installation instructions</h2>

      <p>Install <code>ngx-bootstrap</code> from <code>npm</code></p>
      <pre class="prettyprint lang-bash prettyprinted"><span class="pln">npm install ngx</span><span class="pun">-</span><span class="pln">bootstrap </span><span class="pun">--</span><span class="pln">save</span></pre>

      <p>You will need bootstrap styles (Bootstrap 3)</p>
      <pre class="prettyprint prettyprinted"><span class="com">&lt;!-- index.html --&gt;</span><span class="pln">
</span><span class="tag">&lt;link</span><span class="pln"> </span><span class="atn">href</span><span class="pun">=</span><span class="atv">"https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/css/bootstrap.min.css"</span><span class="pln"> </span><span class="atn">rel</span><span class="pun">=</span><span class="atv">"stylesheet"</span><span class="tag">&gt;</span></pre>

      <p>Or Bootstrap 4</p>
      <pre class="prettyprint prettyprinted"><span class="com">&lt;!--- index.html --&gt;</span><span class="pln">
</span><span class="tag">&lt;link</span><span class="pln"> </span><span class="atn">href</span><span class="pun">=</span><span class="atv">"https://maxcdn.bootstrapcdn.com/bootstrap/4.0.0/css/bootstrap.min.css"</span><span class="pln"> </span><span class="atn">rel</span><span class="pun">=</span><span class="atv">"stylesheet"</span><span class="tag">&gt;</span></pre>

      <p>To enable bootstrap 4 theme templates in ngx-bootstrap, please read <a href="https://github.com/valor-software/ngx-bootstrap/blob/development/docs/getting-started/bootstrap.md">here</a></p>
      <pre class="prettyprint prettyprinted"><span class="com">&lt;!-- index.html --&gt;</span><span class="pln">
</span><span class="tag">&lt;link</span><span class="pln"> </span><span class="atn">href</span><span class="pun">=</span><span class="atv">"https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/css/bootstrap.min.css"</span><span class="pln"> </span><span class="atn">rel</span><span class="pun">=</span><span class="atv">"stylesheet"</span><span class="tag">&gt;</span></pre>
      
      <h3>Setting up the bootstrap version manually</h3>
      
      <p>Sometimes, your project might contain some library that could interfear with the bootstrap framework, or you might have a customized version of bootstrap. The consequence is that the process of determining bootstrap version might be failed, which can break the UI. In that case, we can still set the bootstrap version manually in the boostraping component (i.e. <code>AppComonent</code>):</p>
      
      <pre class="prettyprint lang-js prettyprinted">
<span class="kwd">import</span><span class="pln"> </span><span class="pun">{{'{'}}</span><span class="pln"> setTheme </span><span class="pun">{{'}'}}</span><span class="pln"> from </span><span class="str">'ngx-bootstrap/utils'</span><span class="pun">;</span>
<span class="pln">&nbsp;</span>
<span class="lit">@Component</span><span class="pun">({{'{'}}</span><span class="pln">&hellip;</span><span class="pun">{{'}'}})</span>
<span class="kwd">export</span><span class="pln"> </span><span class="kwd">class</span><span class="pln"> </span><span class="typ">AppComponent</span><span class="pln"> </span><span class="pun">{{'{'}}</span>
<span class="pln">  constructor</span><span class="pun">()</span><span class="pln"> </span><span class="pun">{{'{'}}</span>
<span class="pln">    setTheme</span><span class="pun">(</span><span class="str">'bs3'</span><span class="pun">);</span><span class="pln"> </span><span class="com">// or 'bs4'</span>
<span class="pln">    <span class="pln">&hellip;</span></span>
<span class="pln">  </span><span class="pun">{{'}'}}</span>

      <h2 id="accessibility">Accessibility</h2>

      <h3>Overview and Limitations</h3>

      <p>The overall accessibility of any project built with ngx-bootstrap depends in large part on the author’s markup, additional styling, and scripting they’ve included.
        However, provided that these have been implemented correctly, it should be perfectly possible to create websites and applications
        that fulfill <a href="https://www.w3.org/TR/WCAG20/"><abbr title="Web Content Accessibility Guidelines">WCAG</abbr> 2.0</a> (A/AA/AAA),
        <a href="https://www.section508.gov/">Section 508</a> and similar accessibility standards and requirements.</p>

      <h3>Interactive components</h3>

      <p>Interactive components—such as modal dialogs, dropdown menus and custom tooltips—are designed to work for touch, mouse and keyboard users.
        Through the use of relevant <a href="https://www.w3.org/WAI/intro/aria"><abbr title="Web Accessibility Initiative">WAI</abbr>-<abbr title="Accessible Rich Internet Applications">ARIA</abbr></a>
        roles and attributes, these components should also be understandable and operable using assistive technologies (such as screen readers).</p>
      <p>Authors need to include ARIA roles and attributes to more accurately convey the precise nature of their component. </p>

      <h3>Color contrast</h3>

      <p>Most colors that currently make up Bootstrap’s default palette—used throughout the framework for things such as button variations, alert variations, form validation indicators—lead to <em>insufficient</em> color contrast (below the recommended <a href="https://www.w3.org/TR/UNDERSTANDING-WCAG20/visual-audio-contrast-contrast.html">WCAG 2.0 color contrast ratio of 4.5:1</a>) when used against a light background. Authors will need to manually modify/extend these default colors to ensure adequate color contrast ratios.</p>
